Reconstruct a laser puzzle given the following information:

1. There are seven targets in a 5x5 space on a grid and there are no barriers.
2. There is at least one target in each row and in each column of the 5x5 space.
3. If two targets lie on the same line (vertically, horizontally or diagonally) there will be at least one more target along that line.
4. There is one laser and it first enters the 5x5 space vertically at the top of the center column.
5. Three 45/135 mirrors are used to redirect the laser through all the targets. (Targets may be hit twice.)
6. The laser hits more than one target before hitting the first mirror.
7. The laser and mirrors may be outside the 5x5 space which the targets are in.

Note: A 45/135 mirror is a mirror which reflects a beam at a 45 or a 135 degree angle.
